It is desirable that the powdered base entangle a deodorant material and a powder material, when used with the deodorant mathereon.

On the other hand, it is decarried as by mere entanglement with the nusirable that the powdered base material, together merous pliable fibers extending from the pufi so with the deodorant chemicals, be adapted for as to be readily detachable from the fibers upon ready detachment from the fibers of the puff applying the puff to the skin. It is apparent upon applying the puff to the skin so that the 55 powdered base material and deodorant material may be readily removed from the puff and deposited on the skin. As aforesaid, I have found, as a result of much experimentation, that calamine has the foregoing desirable properties and in a very high degree. In addition to calamine, zinc oxide may be used as a powdered base material, but it is somewhat less satisfactory than calamine. Zinc oxide is, however, distinictly superior to other powder materials, such as those materials hereinabove mentioned, which are commonly used in face powders. Moreover, calamine and zinc oxide are distinguished by a pronounced drying quality and are advantageous for this reason in a deodorant puff according to my invention.

Further features of this invention relate to the deodorant materials that are used. I have found that benzoic acid and salicylic acid are desirable inasmuch as these substances exercise a deodorant effect on perspiration and are relatively nonirritating to the skin. Tannic acid, tannic acid salts, aluminum sulphate and zinc salts such as zinc sulphate and zinc sulpho-carbolate are also desirable and, due to their action in precipitating the albumen of the skin, they have the property of preventing or reducing perspiration and of acting as deodorants in this manner. It is desirable to employ deodorant material part of which is a substance that acts primarily to remove the odor of perspiration and another part of which is a substance that is an anti-perspirant and prevents perspiration.

Thus I have found it to be especially desirable to use substances adapted to remove odor from perspiration such as benzoic acid and salicylic acid and mixtures thereof in combination with substances adapted to prevent perspiration such as tannic acid, tannic acid salts, zinc salts and mixtures thereof. Tannic acid salts such as tannoform (tanninformaldehyde) are illustrative of tannic acid salts which may be used. Zinc salts such as zinc sulpho-carbolate, zinc sulphate, etc. are illustrative of zinc salts which may be used.

While any of the deodorant materials above mentioned can be used alone, the use of one substance alone requires, to be effective for the purpose, the use of the substance in an amount which is somewhat irritating to the skin. I have found that instead of using one substance as a deodorant material, several deodorant materials can be combined to advantage. For some reason the combination of several deodorant materials is less irritating to the skin than a corresponding amount of one of the materials used alone. In preferred practice I employ a plurality of the substances above mentioned, e. g., benzoic acid, salicylic acid, benzoin, zinc sulpho-carbolate, oxyquinolin sulphate, etc, and a substance selected from tannic acid and tannic acid salts, and thereby afford a mixture which has a powerful deodorant effect and which is not irritating to the skin. Moreover, these materials have the important advantage that they do not injure the fabrics such as silk, cotton, etc. out of which garments are made and do not injure the material out of which the foundation member of the puffs is made,

The following are certain illustrative embodiments of this invention, the materials recited being in each case carried by fibers extending from a soft and pliable foundation member.

aromas Per cent (1) Powdered base material selected from calamine, zinc oxide, and mixtures thereof 70 to 90 Odor removing substance selected from benzoic acid, benzoin, salicylic acid and mixtures thereof- Anti-perspirant substance selected from the substances tannic acid, tannic acid salts, zinc sulphate, zinc sulpho-carbolate, aluminum sulphate, oxyquinolin sulphate and mixtures thereof Powdered base material selected from calamine, zinc oxide and mixtures thereof 70 to 90 Benzoic acid to 2 Salicylic acid to 2 Zinc sulpho-carbolate 2 to 15 Substances selected from tannic acid, tannic acid salts and mixtures thereof to 5 The manner of manufacturing a deodorant puff is also part of this invention. I have found that it is preferable to make a deodorant puff embodying this invention by mixing a powdered base material, such as calamine, zinc oxide, or a combination of these materials, together with the deodorant materials and making a semi-fluid mix thereof by the use of a volatile liquid. The resulting mixture may be somewhat like a thin paste and may be of varying degrees of fluidity. Accordingly, the mixture is regarded as best referred to as being semi-fluid in character. The semi-fluid mixture is applied to the puff in any desired manner, as by brushing or spraying it on the material out of which the puff is made, by pressing or stamping it into such material, or the like. After the paste has been applied, the liquid is caused to evaporate as by exposure to the at mosphere or mild heating in a drying oven, leaving the solids entangled with the fibers extending from the puff.

I have found that especially satisfactory results are obtained when the deodorant materials are caused to be in a state of partial solution in the volatile liquid used in making semi-fluid mixture. If the deodorant materials are caused to go wholly into solution the materials tend to form a skin on the fibers of the puff which makes it difficult to remove the materials from the puff. On the other hand, if the deodorant materials do not go into solution at all the materials do not penetrate into the pufi sufficiently. Accordingly, it is a feature of this invention that the deodorant materials are caused to assume a state of partial solution in the liquid used in making the semifiuid mixture that is applied to the puff so that the materials penetrate into the puff and, at the same time, are deposited thereon in such condition that they can readily be removed upon applying the puff to the skin.

A semi-fluid mix may be made using ingredients such as those herein above mentioned and a mixture of alcohol and water may be used as the liquid for forming the paste. The alcohol (ethyl alcohol) is a solvent for benzoic acid and salicylic acid. Other similar solvents and appropriate to the deodorant material used may be selected such as isopropyl alcohol, acetone, etc. By way of example, a semi-fluid mixture of calamine, benzoic acid, salicyclic acid, tannic acid, zinc sulpho-carbolate, water and alcohol may be made up wherein the tannic acid and zinc sulpho- Vzt05 carbolate are dissolved in water and the benzoic acid and salicylic acid are only partially dissolved by the alcohol and are substantially insoluble in the water.' If, for example, one part of alcohol is used to three or four parts of water, the amount of alcohol is insufilcient to dissolve all of the benzoic acid and salicylic acid, and about half of the benzoic acid and salicylic acid occur as finely-divided particles in the mix.

When such a composition is made up in the form of a thin semi-fluid mix and is applied to a puff, the deodorant materials together with the calv amine penetrate into the puff so that they become adherent to the fibers extending from the puff and at the same time can be readily removed upon application of the puff, after it has dried, to the skin. Part of the deodorant material such as the benzoic acid and salicyclic acid will be carried as discrete particles on the fibers extending from the puff due to the fact that a considerable amount of these materials has not been dissolved. An additional part of the deodorant material including some of the dissolved benzoic acid and salicylic acid, together with dissolved tannic acid and zinc sulpho-carbolate becomes coated on the calamine base material which in turn adheres to the fibers of the puff. When a puff prepared in this manner is used, the deodorant materials either occurring as discrete particles or as a coating for the calamine are readily detachable from the puff, but at the same time they adhere thereto sufficiently strongly so as to not fall off prematurely. V

The following are illustrations of formulas which I have found to be especially suitable in the preparation of a semi-fluid mix for application to a puff.

Fig. 1 is a plan view of a sheet of material having fibers extending from the upper side thereof;

7 Fig. 2 is a perspective view of an individual puff 6 having fibers extending from one side thereof;

Fig. 3 is a cross section of the puff shown in Fig. 2; and

Figs. 4 and 5 are cross sectional views of modified forms of pufls embodying this invention.

The figures in thedrawing are not intended to show actual proportions but are largely diagrammatic. Referring to Figs. 1, 2 and 3, individual puffs such as the pufi shown in Fig. 2 may be made from a sheet of material, e. g., from I. the sheet In shown in Fig. 1. The detail of the structure of the sheet l0 and of the pufl shown in Fig. 2, is shown in Fig. 3. The fabric base II has numerous fibers l2 extending from one side thereof. This affords a soft and pliable foundation member for the pufl having fibers extending therefrom which are adapted to carry deodorant material. As aforesaid, the material may be made of cotton, wool and the like and may be formed in any suitable manner as by weaving, felting, or the like. The individual puff may be round as shown in Fig. 2. A plurality of individual puffs may be stamped or otherwise cut out of the sheet III, for example, as indicated by the dotted lines in Fig. 1. Likewise a plurality I of puffs may be formed substantially simultaneously from a plurality of superposed sheets such as the sheet In. While a round puff is shown in Fig. 2, the puffs may be square. If the puffs are square the sheet l0 could be cut into strips longitudinally and laterally so as to result in a plurality of individual square pufis. In general the pufis may be any shape that is thought desirable. In making the puffs the deodorant material may be applied before the foundation member for the finished puff is cut from a large sheet or after the individual puff has been made. In either case a semi-fluid mix comprising liquid, a powdered base material and deodorant materials is made up and applied to the fibers extending from the soft and pliable foundation member as by brushing, spraying, pressure application, or the like. After the liquid has evaporated the fibers of the foundation member carry the deodorant composition l6 (as indicated by the stippling.

In Fig. 3 a pull is shown having the fibers extending from one side only. In such case the back of the puff may carry a suitable trade name l3 of any desired character, directions ll, ornaments l5 and the like, as may be desired, and all of which may be referred to generally as legends.

In Fig. 4 a modified form of puff embodying this invention is shown. In this case, a foundatending from both sides thereof. The deodorant material I9 (indicated by the stippling) is, however, carried on one side only of the puff. This is advantageous as the fiber on the back of the puff which does not carry the deodorant material can be used either to wipe off the skin before the deodorant is applied or to smooth over the deodorant after it has been applied from the other s'de of the puff.

In Fig. 5 a further modification is shown which is similar to that described in connection with Fig. 4 in that the foundation member I I has fibers l8 extending from both sides thereof. However, in Fig. 5 the deodorant material I9 is applied to both sides of the puff. This construction is ad-- I vantageous when a maximum of deodorant is to be carried on a single puff.

Deodorant puffs embodying this invention can be made of any suitable color and the color may be applied to the foundation member of the puff or to the materials adherent thereto, namely, the powdered base material or the deodorant material or both. In such case flesh tints can be had as may be desired by the user. Likewise the deodorant puff can be caused to carry perfume.
